Hmmm. My blue dragon male from Smilesbetta (I know is a different breeder) Aside from poo, and the color seems to be acting somewhat similar? He's acting a lot better today, but the past two days when the light was on he did nothing but sleep, and barely hold himself upright, and his a pink tinge to the white on his fins, and seems skinny.
Somethin' going on across seas maybe? My red copper marble dragon is fine, no white, just lazy I assume (he is the biggest and his fin-span is huge!) however, he doesn't want my pellets, my betta min, or blood worms. The only thing I can get him to eat is mosquito larva.
